UNITED STATES PATENT .Qrrrcn JAMES A. CUTTING, OF BOSTON, MASSACHUSETTS.

lIViPROVEIVIENT IN PHOTOGRAPHIC PICTURES ON'GLASS.

Specification forming part of Letters Patent No. 11,267, dated July 1]., 1854.

To all whom 'LZT may concern:

Be it known that I, JAMES A. CUTTING, of Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Photographic Pictures on Glass; and I do hereby declare the following to be an exact description thereof.

The nature of my improvement consists in the application of a coating oihalsamnoflfir to the side of the glass on which the picture is made, over which coating Iplaceanotherglass of equal size with the one on which the picture To enable others skilled in the art to make and use my invention, 1 will proceed to describe the process, as follows:

After thoroughly cleaning a glassflplate of the same size as that on yvhich the picture to be secured is made, and removing all dust from the picture, I hold the glass containing the picture in a horizontal positionwith the pictured side uppermost, then apply the balsam in a line along one edgeof the glass, and placing one edge of .the secondglass in close contact with the edge of the first containing the. balsam, press them gradually together toward the opposite edge, causing the balsam to flow by a gentle pressure toward the opposite edge, in this manner excludingall air. from between the glasses, then by an even pressure exclude the superabundant balsam.

The advantages of my improvements are that by a mechanical combination ot' the balsam with the pictnrelit is greatly increased in strength and beauty by an ad diti'onal brilliancy andthe exhibition ofmthe most minute "dolineations, and by the application of the second glass, in GQIQbltlation withthebalsam, the picture is..,.h er etically sealed and rendered entirely pe pent by beiu" ;d:"i?om the infiuencebf tnre aud also from injury by dust "61' other extraneous matter, or acidiapors,orahyyiolericathan what would occasionlLhefr-actnre of the glass plate. I am aware of the previous use of balsam for the cementing of lenses and the, securing of microscopicpbjectsfiumlilie purppses, and do not therelore egte nd my claim to any ofthese uses; but y What I claim as my invention, and desire to secure by Letters Patent, is-

The combination of balsam with photographic pictures on glass, and with the additional glass, by which they, with the balsam, are hermetically sealed, as described in the specifications, and for the purposes therein set forth, and for no other.
